IMPROVEMENT IN DESK SLATE-HOLDERS.

Specification forming part of Letters PatentZNo. 183,157, dated October10,1876; application fi ed June 14, 1876.

To all whom it may concern:

Be it known that 1, JOHN HAGGERTY, of Corry, in the county of Erie andState of Pennsylvania, have invented certain new and useful Improvementsin Noiseless Desk and Revolving Copy-Holder; and I do hereby declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the .art to which it'pertains tomake and use it, reference being had to the accompanying drawings, whichform part of this specification.

The nature of this invention consists in the construction andarrangement of a noiseless writing and drawing desk with revolvingcopy-holder, as will be hereinafter more fully set forth.

In the accompanying drawing, which fully illustrates this invention, Arepresents the box or frame of the desk, constructed of any desired sizeand of about the usual form. The entire box or frame A is covered withfelt B, or other similar material, preventing all noise in moving thedesk.

In the back or highest part of the desk is a rotating spool, consistingof a shaft, 0, with heads or disks D D secured thereon. The shaft 0passes through the sides of the frame A, and has knobs E secured on itsends, and the disks D D are fastened on the shaft within the box andclose to the sides thereof.

In the inner sides of the disks 1) D are made grooves a a, to receivethe copy-plates G G, either one of which can be brought into view byturning the spool by means of one of its knobs, such plate beingimmediately back of the slate, or rather above the same, the top of thedesk being left open at that point, as shown, for such purpose. Withinthe box A are inclined racks H H, to hold the copyplates G, when not inuse, in the revolving spool. At the front, within the desk, is fasteneda rack, I, for holding slate-pencils, said rack being provided withelastic bands b b, under which the pencils are placed, and by which theyare held in place.

The top of the desk is formed of an ordinary slate, J, inserted in agrooved wooden frame,

L. This frame L is entirely covered with strips d d, of felt or othersuitable material, the edges of which are folded into the grooves in theframe, and held there by the slate entering said grooves, where theframe is put around the same and fastened. At the corners the strips dare sewed or otherwise fastened together with felt beads or ridges e e,attached thereto as shown. The slate-top J L is held at the back edge bytwo projecting moldings on the box or frame, and at the front by aspring-catch, R. It is prevented from moving laterally by a knob orsmall projection, 2', in the slate-frame entering a recess, J0, in thespring-catch.

By the felt-covering d being inserted in the groove of the frame allrattling of the slate in the frame is effectually prevented, thecovering also preventing noise against the desk. The felt beads orcorners e, in addition, prevent any sudden shock to the slate onfalling, and help to prevent noise against the desk.

The entire slate is easily detached when required for use as aschool-slate.

Having thus fully described this invention, what is claimed as new, anddesired to be secured by Letters Patent, is-

1. A writing and drawing desk for schools, composed of a frame, A,entirely covered with felt B, or other similar material, and having aremovable slate-top, as herein set forth.

2. The rotating cop v'holder, consisting of the shaft 0, with grooveddisks D1), arranged within a desk-frame, A, substantially as and for thepurposes herein set forth.

3. The combination of the desk-frame A, with felt covering B,copy-holder U I), inclined racks H, pencil rack I, with elastic bands bb, and the noiseless slate-top J L, with springcatch R, substantially asand for the purposes herein set forth.

In testimony that I claim the foregoing I have hereunto set my hand this5th day of May, 1876.

JOHN HAGGEItTY.
